you can get any of the available skins quite easily, no need for special backup.

go to settings, appearance, skin, wait a few seconds for the list to come out, choose what u want.

what do u mean by "original menu"?

u mean every repo, addon u added, enabled or preinstalled?

how did u lose that in the first place?

ah, i think i know what u mean...

u had an customized superbox mimic v2 that came with the box.

u pressed the skin reset, correct?

the reset removes all the customized skin settings for font, vertical/horizontal, colors, shades of black, etc., back to defaults.

once u do that, they are gone - u will need to rebuild the skin settings/subsettings one by one if u want it.

not too difficult, i tried it before. can actually be fun to build it to yr own taste.
just curious... assuming yr box is quite new... can u check this superbox build version u have, is it dated 18 may 2016?

if yes, it confirms there is no more update since then... which is no good... i already stopped using this build.

which skin r u on now?

.. if on mimic v2, it is under a special option in the main menu where u get to update the build - open that and see if what version u on, what is available.

.. if confluence, u can see it in settings... one of the options there.

a build skin has only a few differences with the basic confluence, esp the look, background and colors; structurally, all the rest are still the same.

ok, never mind.

as long as u are now happy with a new build!

one thing u may want to check...

depending on how you "reset" kodi before u reinstalled some other build, i.e. removed everything totally or kept the user data folder, some kodi files/folders can stay on in the memory incl kodi recycle bin, taking up memory.

superbox build can take up to 2gb memory whereas a typical average build is <1gb.

yr g5pro has only 8gb total, so do check this bit.

can check with es file explorer.

that is to be expected from a 2/8gb box net of opsys and apps.

it's fine for most purposes, except for torrent based apps that need big memory to work, e.g. popcorn time and kodi/quasar.

it is for this reason i did not buy this model alto i really want the hdr/60fps/10bit/dtsx capabilities.

now waiting for an upgrade version, hopefully a "q5iipro 2/16gb android 6.0"!
